I am getting Error - More than one content model is assigned the guid


Hello!   I am getting Error "More than one content model is assigned the guid 7e932eaf- .....

I know why I am getting it. I had one namespace (example Project1) and that I changet it (to Project2). But in database I still have all my Page types, blocks with first namespace. Thats why I am getting this oene error. Its important to have new namespace. How can I fix this ?  Any ideas ?

It looks like you accidentally assigned same GUID to two strongly typed types. Take the guid in the exception and find in entrire solution to see which types are using that, then change one of them.

@Quan Mai right, I have one page type (StartPage with GUID) in database (table [tblContentType] namespace Project1) but then I changed Project Name and now I have namespace Project2. So I have the same page type StartPage with the same GUID but with new namespace. So how can I fix this? I guess I can Replase Namespace in database , but I am not shure that this will fix my error.

Why don't you just change the GUID of StartPage? It's easiest option, is there anything prevent you from doing that?

Other option should be go to Administration view and delete the old start page type.
